* Remove the use of CDN and bundle everything inside the app. We still pre-build the prefetcher because it needs different webpack config which only targets browsers supports Service Workers. * Remove cdn config item. We no longer using it. * Stop adding script tags when staticMarkup=true * Remove babel-plugin-transform-remove-strict-mode NPM module.
